SPACING DEVICE FOR WARPS.

Specification oi Letters Patent.

Patented May 11, 1909.

Application filed December 3, 1906. Serial No. 346,171.

To all whom 'it may concern:

Be it known. that l, JOHN G. GounnnAU, ya citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Spacing Devices for Wlarps, of which the YFollmving is a specification.

My invention relates to devices for spacing the yarn in warps, and it is used in connection with looms, slashers, drawing in machines for harnesses, and other machines in. which warps are treated. It is especially adapted for spacing and holding the metal teeth or dents oi reeds and of lease combs and slasher combs.

This invention is an improvement upon the construction for which application `was made by me August 2a, i906, Serial Number It consists,

1principally, in the substitution for the coi of round wire shown in that patent, of a coil of flat wire curved edgewise dents and the loops, instead of being tangen tial, is iiat, and because there is a consider ably greater depth with very little width of metal between the dents, thus making a stronger construction than the other. Moreover, if a small wire is wound upon a large mandrel, the resulting coil has no strength nor [irmness, but if it is wound upon a small mandrel, the resulting coil is much stiffer. However, if dents are placed between the loops of a coil ot small diameter, the points of contact are nearer together and the dents are not held so stiflly. Besides, in reed making, it a coil of small diameter is used, it must be built up by wooden or metal strips to form a reed cap of the desired size to lit the groove in the lathe. By using my device, a coil of any desired size can be used and no building up for the reed cap is necessary.

ln the drawing, Figure l is a front view ofl the end of a reed. F ig. 2 shows a section of l? ig. 1 on the line lU V. Fig. 3 is an enlarged view showing the manner in which the coiled llat wire incloscs the rib to which is is to be soldered. l? 4- shows the actual position of the loops ol' the coil after they have been placed and soldered to the rib, and shows a few dents in place. Fig. 5 shows the end of a reed. 'wherein the wire coil is soldered to both ribs. Fig. 6 is a section of Fig. 5 on the lint.` Y. Fig. 7 shows an adaptation of my device to the ends onl of a reed. Fig. Y# shows the manner in wliich washers maybe .substituted for a wire coil. F ig. 9 shows the washers soldered in. place.

The principal feature of my invention is the spacing rib which is constructed by winding a metal strip A of substantially rectangular cross section edge-wise about a mandrel of the desired size into a spiral coil. This coil A is then passed over a segmental spacing rib B, as shown graphically in Fig. 3. The distances between the loops of the coil are then spaced in a suitable manner, as by the insertion of the teeth of a comb between them. This process changes the regular spiral curve into a series of parallel flat loop sections connected by curved or slanting sections, as shown by the dotted lines in Fig. 4. The coil A is then soldered to the curved sur face of the segmental rib B, as shown in Fi 4. To build a reed, two of these ribs B wit inclosing coils A are laced parallel with each other and at a suita le distance.

The dents D which consist of flat strips of metal preferably provided with uniform slots or notches 11 of about the length of the inside dianieter of the loops of colls A are then inserted between the loo s of coils A.

jtetaining ribs (l are t ien passed over the dents and through the slots or notches therein and through the loops of coils A. The up er and lower sets of segmental ribs, with inc osing coils, are connected by end feces F fastened to ribs B and C by screws or by other suitable means.

It can be readily seen that as the loo s of the coil A are flat and the cross section o the dents D is flat, when the dents are in place, they form together a substantially solid piece notches l] near the endsl of the dents and i thus the whole construction is substantially sohd, see Fig. 4.

cross section which rise above the l'lat surluce thereof.

L?. ln o dent holding device, a segmental sluiting' ril) 'lo which :Ire hastened a serie-i of The lat wire coil permits a niueh smaller spare being allowed between thc dents and, :is the dents themselves cnn be huido very thin, a much larger number ol' counts to the inch is possible.

Figs. and [i show u. soldered reed ol' similar construction. In this construction, both the segmental rib Il with the coil ol' wire A,

the retaining ril) (l and that part ol' the dents l) comprised therein all in place, are dipped into the solder, thusI forming' a solid mass. In this ease, the dents are not detachable, but the reed is very stilla and strong, and by this process, reeds of very vline counts can be built. In such reeds, the ribs should 'fit closely the spaces between the dents and the inside of the coils to obtain the strongest construction.

In some kinds of weaving, rmiably in the case of silk, the selvziged edges ol. the warp, where the threads are doubled, Wear out the dents at each end of the reeds much more rapidly than those in the center. 'l`o niect this Condition, I build a reed, as shown in Fig. T, wherein one rib Cr is of metal and throughout the central portion the, other rib H is of wood. In the central portion., the dents J pass between these two ribs and are held in place by the usual pitch band construction. At each end, however, I solder coils of flat metal wire A, as in the iirst construction described, and place the dents D between the loops thereof. I hold the dents in place by ineens of short sliding ribs Ii which are themselves held in place by suitable screws L. Instead of the pitch band construction, I een use in the middle portion of the reed, the solid soldered metal con struction, shown in `Figs. 5 and or any other similar construction, in which the dents are not readily detachable.

Instead of using the coil of flat metal wire in the construction of my spacing device, .l can use a series of indeiiendent washers M which are slipped over the segmental rib N, as shown in Fig. 8. These washers M are closed up and suitably spaced and are then soldered to the curved surface of the segmental spacing` rib N, as shown in Fig. 9. The result of this construction is that loops of flat wire project above the flat portion of the segmental spacing rib the same as where the continuous coil .is used, but I iind that it is easier to construct the spacing' rib by using the coil.

What I claim as my invention and desire to cover by Letters Patent is:-
